HARROW.

Specification of Letters Patent.

Patented Dec. 15, 1914.

Application filed December 19, 1913. Serial No. 807,636.

My invention is an improvement in 'harrows, and has for its object to provide a device of the character specified, especially adapted for use with a cultivator and of any construction, and wherein the construction is such that the harrow may be used as close to the plants as may be desired, and

wherein the harrow may be guided with the handles of the cultivator in the same man ner as the ordinary shovels are guided, and wherein the harrow may be cleaned, merely by lifting it to permit foreign matters to drop away from the teeth.

In the drawings :Figure 1 is a plan View of the improved harrow, Fig. 2 is a section on the line 22 of Fig. 1, Fig. 3 is a perspective View of a portion of the harrow showing the manner of connecting the teeth. and Fig. 4 is a section on the line 44 of Fig. 3. i

The present embodiment of the invention comprises side bars or members 1 and 1 of angle material, and arranged with one of the angular portions vertical and the other horizontal. The bars or members 1 and 1 are arranged at an angle to each other as shown in Fig. 1 and they are connected at their front ends by means of a plate 2.

The plate 2 is provided with an angular upwardly extending lug 3 at its front end, for a purpose to be later described, and the bars 1 and 1 are connected to the plate 2 by means of bolts 4. The plate 2 is arranged beneath. the bars 1 and 1 and the bolts 4 are passed upwardly through the plate 2 and the horizontal portions of the angle bars and are engaged by nuts 5, above the said portions. 7

A cross plate 6 is arranged between the bars intermediate their ends, and the said cross plate is provided at each end with an angular portion 7, the said portions extending at an obtuse angle with respect to the body of the cross plate. Each of the extensions 7 is provided with a longitudinal series of openings 8, and the said openings are adapted for engagement by bolts 9, which are passed upwardly through an opening of the extension and through the horizontal portion of the angle bars and are engaged by nuts 10 above the horizontal portion. A drag bar 11 is connected with the plate 2 and withthe cross plate 6, the former connection being made by the bolts 4, while the latter is made by a bolt 12. The bolt 12 is passed downwardly through the drag bar and the cross bar 7, and is engaged by a nut 18 below the cross plate. The front end of the drag bar is offset downwardly, as shown 1n Fig. 2, and fits between the plate 2 and the horizontal portions of the side bars. In rear of the cross plate 6'the angle-bar s bent upwardly at an angle to the body thereof as shown at 14, and the said bent up portion is provided with a longitudinal series of openings 15". The portion 14 of the bar is also arched transversely as shown in Figs. 1 and 2, the convexity of the arch being upward. Teeth 15 are connected withthe angle bars 1 and 1 and with the portion 3 of the plate 2, the said teeth being connected with the vertical portions of the angle bars. The teeth are connected to the angle bars by means of blocks 16, each of the said blocks being rabbeted on one face as shown at 17, and having a transverse groove 18 on the other face. The blocks are slightly wider than the vertical portion of the angle bars, and the rabbeted portion is deep enough to receive the said vertical portion of the angle bar. The shoulder 19 formed between the rabbeted portion and the main portion of the block rests upon the upper edge of the said vertical portion of the angle bar, and the groove 18 is transverse to the said shoulder. The grooves 18 are of a width to receive the teeth 15, and a bolt 20 is passed through an opening through the block near the groove 18 and through an opening in the vertical portion of the angle bar and is engaged by a nut 21 to clamp the tooth and the block in place. The head of each bolt over-lies the adjacent tooth, and the groove 18' is of less depth than the thickness of the tooth, so that the outer face of each tooth extends beyond the outer face of the adjacent block. The blocks 16 are of rhomboidal form as shown, and the groove 18 is inclined, so that the teeth incline downwardl and rearwardly as shown in Fig. 2. A tooth 15 is also connected with the portion 3 of the plate 2, the said portion 3 having in one side face a groove 22 parallel with the groove 18 of the blocks. The tooth 15 is arranged in the groove 22,-and a bolt -23 -is passed through the portion 3 of the plate adjacent to the groove, and the said bolt is engaged by a nut 24: on the opposite face from thetooth, "The head i of the 1 bolt over-' lies the outer face of the tooth, and the groove 22 is of less depth than the thickness of the tooth, so that the outer face of the tooth is beyond'theadj'ac'ent face of'the extension. WVhen the nuts5 are loosened,'an d the bolts 9' are removed3the anglebars l' and 12 may be adjusted with respect to each other to eausethern to diverge'fat a greater or less' a'ng'lewith respectto each other.

It will be understood "that "the improved barrows 'will' in'practice be used in a pairs, in the same'manner asthe cultivating shovels, and the frames will take the place, of the usual supporting frames "for the cultivating teeth, The respective framesYare moved by means of'the usual handlesin connection with the cultivator, and are cleaned lifting the supporting frames. When moving from field to fieldQthe'fra'meS ma'y'beturned withtheteeth out of engagement with the ground. The particular mechanism for .connectingthe teeth with the 'side'bars'provides a secure connection that will "prevent any twisting or rearwardmovementof the lower Copies 6! thiajatezit' mai-be obtained for end of the tooth, while atthe same time permittingthe vertical adjustment of the teeth.

As the teeth become worn, the holding bolts m'ay be released to permit further downward movement of the teeth, and'the teeth mayb'eieasily removed when broken or for any other reason.

In a barrow, the combination with the frame and the teeth, of a block arranged between eaoh tooth and the 'framefor connectthe tooth and the frame, each block being r'abbeted 'on'oneface and-having atransverse groove 'on' theoth'er face, thefblock having a shoulder between the rabbeted portion andthemain'portion *for connecting a tooth to the frameto hold the block from downward movement, and the-groove in- I the head of'the bolten'gagingthe outer face (if the'toot'h, and a nut engaging the bolt.
